Abstract: 1317014 Semi-conductor devices RCA CORPORATION 3 July 1970 [11 July 1969] 32388/70 Heading H1K Electrical conductors on a SiO 2  layer 16 passivating the surface of a semi-conductor device such as the Si planar transistor illustrated comprise layers 24a, 24b of Si on which, are deposited layers 32, 34 of Ni and layers 36, 38 of P6 solder; e.g. 1-5% Sn, 99-95% Pb. The Si layers 24a, 24b may be monocrystalline, deposited by reduction of SiCl 4 , or polycrystalline, deposited by decomposition of SiH 4 , the latter being particularly useful if it is desired to provide an emitter ballast resister in the emitter contact opening 18 of the SiO 2  layer 16. For the base contact the Si layer 24a may, as shown, stop short of the contact opening 20, the actual contact being made by the Ni layer 32. The Si layer 24 from which the layers 24a, 24b are formed is initially deposited over the entire SiO 2  layer 16 and is selectively etched to shape using a photo-resistively defined, and subsequently removed SiO 2  mask. The Ni layers 32, 34 are formed by electroless deposition and the solder layers 36, 38 are applied by dipping after the application of a flux.

Title: Internal combustion engine exhaust heated de-icing means applicable to aircraft
IPC: B64D15/02
Filed: 1939-12-23
Abstract: 536,343. De-icing aircraft. JAMESON, R. W. Dec. 23, 1939, Nos. 32829/39 and 17760/40. [Class 4] De-icing means for aircraft in which air circulated through the wings, fuselage, fins or tail, or through all of such parts is drawn through a chamber or chambers surrounding the stubs of the exhaust pipes or other parts of the engine exhaust conduits, has means for admitting cooling air to the chamber or chambers when air is not being circulated for de-icing purposes. In one form a casing 3 surrounds the exhaust stubs 1 and manifold 2 which is provided with pins 2d to increase the heating effect. Air is drawn into the casing through openings 3a and out through a pipe 4 from which the heated air is distributed to the leading edges of the wings, along the fuselage to the leading edges of the tail planes and finally discharged at the rear of the fuselage. A forward opening 3c is normally closed but is opened to admit cooling air to the casing when ice-forming conditions are not present. Fig. 8 shows a device comprising a slide 7 for effecting the alternate opening and closing of the pipe 4 and orifice 3c, an opening 7e in the slide becoming coincident with the bore of the pipe 4 when the orifice 3c is closed. The slide 7 carries a contact 7b which engages a contact 7c to start an electrically driven fan 5 for circulating the heated air when the pipe 4 is opened. Alternatively the opening 3c may be controlled independently of the pipe 4. A propeller driven fan at the end of the fuselage may be used to circulate the heated air in which case a switch 8 is opened to cut out the motor driven fan. In a modification the conduit 4 leads from a cap normally closing the orifice 3c a section of the conduit being hinged so that the cap can be withdrawn from the orifice. In a further modification, Fig. 10, the air after circulation is returned to the casing 3, both the pipe 4 and the return pipe 4a which is of larger diameter being extended into the casing, where they are arranged concentrically. Circulating fans may be placed at various points to aid in the distribution of the heated air. The motor driven fan 5 may be controlled by a thermostat. To increase the moisture content of the heated air water may be caused to drip on the fins of the exhaust manifold from a pipe fed from a tank.

[Also in Division H2] A gas-burning torch includes a piezo-electric crystal 83 for producing an ignition spark across a gap in its nozzle D. The crystal 83 is contained in, and insulated from, a cylinder 81 screwed into a valve housing A, and is compressed by a plunger 90 slidable in the cylinder 81 by a cam mechanism 82 comprising an operating plunger 102 and a cam block 96 having disposed therebetween a spring-urged roller 94. The plunger 90 engages a rubber pressure pad 87 separated from the piezoelectric crystal 83 by a pressure disc 89 and an insulation disc 88. The cam block 96 has an inclined and a bottom surface which coact with the roller 94 to cause the plunger 90 to move first gradually towards the crystal and then abruptly away from the crystal, as an operating plunger 102 is raised by a handle E pivoted to the housing A. The abrupt release of the plunger 90 from the crystal 83 generates a voltage in a wire 85 connected at one end to the crystal contact base 86 and at the other end to one side of a spark gap in the nozzle D. The handle E also coacts with valve-operating plungers 31 (not shown), 46 and 60.which control respectively the oxygen, gas and cutting oxygen valves. The oxygen cutting valve 54 (Fig. 3), comprises a head 57 biased to the closed position by a spring 59 and having a bore 58 which slidably receives the shank 61 of the plunger 60. The oxygen and gas valves are of similar construction. Two adjusting valves (Fig. 7, not shown), are provided in the valve housing A for regulating the proportion of oxygen and gas. A mixture plug 142 is threaded into the torch head B, Fig. 9, and has a chamber 144 for gas supplied from a tube 110, and a chamber 147 for oxygen supplied from a tube 112, the tubes being connected to the valve housing A. The mixture passes into a passage 179 in the nozzle D which is formed by an outer sleeve 160 electrically insulated from an inner core 170 connected to the wire 85 and having an axial oxygen-cutting passage 174. An outlet chamber 192 is provided between the lower portions of the sleeve and core, the spark gap being defined by the gap between the peripheral edges thereof. In Figs. 16-19 (not shown), various arrangements of nozzles are depicted. In one construction the annular passage for the mixture is divided into a plurality of velocity passages and a bleed passage is provided which connects the velocity passage to the centrally disposed oxygencutting passage. The oxygen cutting passage has a layer of insulation covered by a conductive coating connected to the wire 85 and the spark gap is defined by the periphery of the coating and the inner sleeve adjacent thereto. An outlet chamber may or may not be provided between the lower end of the sleeve and core. In a second construction the spark gap is located in a passageway leading from the outlet chamber.
